Strobe Helm

Strobe Helm is a flash controller you can use with one hand. Connect your Godox XPro II, X3 Pro or X2T trigger over Bluetooth and set every group from your iPhone: power, Manual, TTL or Off, the modelling lamp, the beep and a test flash.

EVERY GROUP AT A GLANCE
A big card for each group shows its power, in fractions (1/8 +0.3) or the 1–10 scale. Drag across a card to change it, or tap − and +. The shift dock moves all groups together, so your ratios stay as they are. Keep a group fixed and it stays put while the others move.

PRESETS
Save a whole lighting setup, star the ones you reach for and switch with one tap. Change something and the app shows it, with Revert and Update one tap away. Share a setup as a QR code or a text code.

THE SHOT LOG
Every setup you send is logged, with the time and the values, so you know which light made which picture.

ON YOUR WRIST
With Pro, the Apple Watch app shows your groups and favourite presets, shifts the power with the Digital Crown and fires a test flash with a long press.

YOUR IPHONE AS A REMOTE
Shooting tethered? Your iPhone joins Strobe Helm on your Mac or PC over the local network and becomes a remote for its lights and its sequences with Lightroom Classic or Capture One (with Desktop Pro on the computer).

TRY IT WITHOUT A TRIGGER
No trigger at hand? "Try Without a Trigger" opens the app on a simulated one, with sample presets and every Pro feature, so you can look around first.

FREE, AND PRO
Everything that controls your lights is free, for good. Mobile Pro is a one-time purchase, no subscription, no account: unlimited presets and undo, favourites, sharing presets as codes and QR, roles, Solo, Keep fixed, links for other apps, and the Apple Watch app.

PRIVATE BY DESIGN
No account, no internet needed, no analytics, no ads. Your setups stay on your devices.

Works with the Godox XPro II, X3 Pro and X2T (Bluetooth). The original Godox X3 has no Bluetooth and can't be used.

Strobe Helm is an independent app. It is not made, endorsed or supported by Godox.
